EUGENE G. REISING, OF EAST HARTFORD, CONNECTIGET.

To all whom it may concern: v

Be it known that I, EUGENE G. REISING, a

of East Hartford, in the county of Hart ford and State of Connecticut,have invented a new and Improved Firearm, of which the following is aspecification. My invention relates to that class of firearms that aresupported on the person when being fired, and an object of my invention,among others, is to so construct such a firearm that it shallbeespecially simple in construction' and effective in operation. y

One form of firearm embodying my invention and in the construction anduse of which the objects herein set out, as well as others, may beattained, is illustrated in the accompanying drawings, in which Figure 1is aview in central vertical section through a firearm embodying myinvention, the front end of the barrel being broken ofi. Y

Fig. 2 is a cross sectional view on plane denoted by dotted line 2-2 ofFig. 1

Fig. 3 is a cross'sectional view on plane denoted by dotted line 33 ofFig. 1, the

i lower part of the handle being broken off.

Fig. 4 is a view in side elevation, of the right hand side of myimproved firearm, the lower part of the handle and the front end of thebarrel being broken ofi' and parts being broken away to showconstruction.

Fig. 5 is a perspective view of the breechbolt.

While my invention 'is not limited to any particular species of firearmyetit is especially adapted for use in that type commonly called apistol. Such a device has been selected by me for the purpose ofillustration and description of my invention herein.

The upper part of the frame of my improved pistol comprises a receiver6, and the lower part of the frame comprises a handle .7 anda triggerguard 8. The device is also provided with the usualtrigger 9, hammer 10,sear 11, magazine 12,1hammer strut 13, strut seat 14, and main 8 ring15, all of which may be constructed 1nany suitable and convenientmanner.

In my improved device there is a spring seat 17 toreceive the thrust ofthe main spring 15 at its lower end,- this spring seat resting against amagazine catch 16, 1n the formof a leverpivotally' mounted in the lowerend of the handle, one end of said Specification of Letters Patent.

lever receiving said spring seat and the other end having a lip .toengage the magazine under thrust of the main spring and a thumb piece bymeans of which the lever may be operated. I

The pistol shown herein is of the break down type, the barrel 18 beingsecured to ceiver to locate a part of the body of the a pin next to thereleasing groove within the locking groove 20 to thereby, lock thebarrelagainst swinging movement on the frame or receiver. A thumb piece 23 issecured to the end of the barrel lock and projects through a recess inthe side of the receiver to a point where it is accessible from theoutside for the purpose of operation. Said lock is seated against a lockoperating sprin 24 located in a recess in the receiver. this descriptionit will be seen that pressure upon the thumb piece23 will move thebarrel lock against the force of the spring 24, and into position toregister the releasing groove 22 with the lug 19, in which. position thebarrel may be swung on its.=.pi vot that secures it to the frame.

A; breech-bolt is slidably mounted on the receiver, said bolt comprisinga body 26 having retaining flanges 27 depending from opposite sidesthereof and breech-bolt retaining bars 28 projecting forwardly from saidflanges and underlying the side edges of the rear end of the barrel thatoverhangs the receiver to an extent substantially equal to the thicknessof said bars, the cross sectional dimensions of the body of thebreech-bolt being substantially equal to the cross sectional dimensionsof the barrel at its rear end whereby the upper part'of the structure issmooth. The upper part of the receiver is cut-away for a portion of itslength to "form a slideway 29 for across piece 30 that i the trigger andextends rearwardly along one side of the magazine and a sear bar 37projects at an angle from the rear end of the trigger bar and inposition to contact with the lower end of the sear 11. A compound springcomprises a base 38 and sear and sear bar springs 39-40 extendingtherefrom, the latter to rest, in contact with the sear bar 37 and theformer to rest in contact with the sear 11. The scar spring structure isof inverted T-shape, the ends of the base 38 projecting beyond thesprings being located in spring retaining grooves 41 located in the rearwall of the magazine chamber, the lower edges of said grooves beingundercut to receive the beveled lower edge of the base, as shown inFigs. 1 and 2 of the drawings.

From this construction it will be seen that the spring structure may bereadily secured in place by inserting the beveled edge of, the base intosaid undercut grooves and then forcing the base and springs backwardlyfrom within the magazine chamber. The pressure of the sear bar and searupon the springs will retain the spring structure in position andagainst any liability of disengagement when the magazine is not inplace, and the magazine when in positionwlll assist in retaining thespring-structure in place.

A safety lever 42 is, pivotally mounted in a recess in the front edge'ofthe handle, the upper end of said lever projecting into the inclosurewithin the trigger guard to engage a notch in the trigger, as shown inFig. 1 of the drawings, a spring underlying the safety lever forcing itinto engagement with the trigger. except when said lever is manuallyoperatedto release it from the trigger. The lower end of this lever isin convenient position to' receive pressure of the fingers of a handgrasping the handle so that when the handle is so grasped in theordinary manner the safety lever will ofnecessity be operated torelease. it from the trigger.

A trigger bar disengaging slide 43 is mounted 1n the receiver wlth oneend located in a recess in the under side of the breechbolt, as shown indotted lines in Fig. 1, and

the other end resting upon. the sear bar 37. When the breech-bolt isforced. backwardly,

this slide is forced downwardly to locate thesear bar below the sear andthus permit. the

latter free movement to quickly. en g1: the' hammer when the latter-isforce ackwardly. This slide 43 is held in place by. a sear in 44 thatprojects through a slot in the slide.

The retainin flanges 27 on the breech-bolt extend below t e upperendgesof the sear pin 44 and the hammer pin 45, which pins are therebylocked in place by said flanges, and the entire firing mechanism isconsequently locked in place by the manually operable barrel lock 21.When said lock is operated to release the barrel, the latter may beswung with its rear end upwardly and the breechbolt may be lifted out ofplace. When the breech-bolt is in place the sear and hammer pins arelocked in'place.

The breech-bolt is provided with a firing pin 46 of any ordinary formand construction and arranged to be struck by the ham- 85 mer when thelatter is released for firing action.

The spring seat 32, in the preferred form of my invention, comprises acollar slidably mounted on a spring su porting rod 47, said collar beingprevented rom moving off the end of the rod in any suitable manner, asby a pin passed through the rod, and the opposite end of the rod may beprovided with any suitable means, as a head, to receive the thrust ofthe spring. This provides a structure that serves its purpose as abreech closer and at the same time one that may be readily removed fromthe firearm without any liability of the spring escaping from itsfastenings. v

The disengaging slide 43 is made from a very thin plate of sheet metalthat may be stamped to shape, and in order that such a slide may beemployed a shallow recess 48 is formed in the'side of the chamber in theframe containing the sear and hammer, said slide being slotted toreceive the sear in 44 upon which the slide is mounted. 'Fhe 'slide thushas simply a vertical movement, 110

the recess forming a slideway and preventing any turning movement of theslide on its pivot.

In accordance with the provisions of the patent statutes, I havedescribed the prin- 115.

ciples of operation of my invention, together with the device which Inow consider" to represent the best embodiment thereof; but I desireto'have it understood that the device .shown is only illustrative andthat the invention may be carried out by other means. p
